Yeah see that's the sort of conclusive mindset that's got us here. I don't mean to insinuate you're wrong for coming to that conclusion, but "It costs money or effort so let's use a worse option because it's convenient" is part of the reason we don't have a lot of good solutions in this domain.

I'll also admit the options these days are limited depending on your goals for a project. If you want to reach the most eyes and have the highest draw of potential contributors, having a discord server makes sense. My gripe is when technical discussion or support take place there.
